Renforcement des berges
Constructed with AZ18-800 Arcelor Mittal® piles of 9m and 11m length. The sheet piles were installed by pair by using a guide which facilitates the verticality of the piles and improve the penetration. The 16HFV Vibrodriver was equipped with a shoeplate designed for AZ large sheetpile to drive in a sandy-clayey gravel soil.
This PTC AZ shoeplate is designed for all AZ sheetpiles and adapted to our medium range of Vibrodrivers up to 75HD, 60HV or 32HFV.
The work were done in mid-tide of the Dordogne River to be able to reach the desired depth needed for the reinforcement.
The river banks were reconstituted by pebble drain, clay embankments, and then by a coconut matting geogrid. A willow cutting will be planted on each linear meter to finish the slope.
